APPARATUS FOR APPLYING MASTIC T0 WALLS.

Specification 0! Letters Patent.

Patented May 29, 1917.

Application filed Ianu cry 2, 1915. Serial No. 208.

To all whom it may concern:

Be it known that I, HENRY VViconnnonn, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented wcertain new and useful Apparatus for Applying Mastic to Walls, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to a temporary structure and supporting means,' whereby I am able to apply a bituminous lining to a vertical or inclined concrete wall. The application of such a linin to concrete walls is useful, as for cxamp e where receptacles, such as resa'woirs or tanks made of cement or concrete, are to be used to hold liquids whichare corrosive in their nature, such as the acid liquids frequently used in metallurgical or other chemical processes.

The present'application is not concerned. with the composition of the bituminous lining. In general it is a mastic-like mixture, of a bituminous cementing material with a mineral aggregate. Such material has already been described by me in an application executed by me and filed simultaneously herewith, Serial Number 20 1-. Such a bituminous mixture is quite fluid when hot, but at atmospheric temperatures sets to form a hard bituminous substance suitable for lining surfaces as above described.

N o particular difliculty is experienced in applyin such a bituminous lining to a substantiall y but with inclined or vertical surfaces or walls, rliflicult'y is experienced because the material as it cools passes too quickly from the liquid to the solid state to permit of its being applied with a trowel as are ordinary mortars or other plastics.

According to my invention, in order to apply such lining to a vertical or inclined wall, lathing st attached to the'wall',

and a temporary structure with a limiting surface erected parallel to the wall at a. distance corresponding to the thickness of the lining which it proposed to apply. The lining is then poured, While hot and fluid, into the space between the wall andthe limitin surface and allowed. to cool and set.

The object of myinvention is to provide a. suitable temporary limiting structure which will successfully prevent the escape of the liquid unite-rial until it has cooled and horizontal surface of concrete,

set; and which may be both easily erected and removed. and capable of repeated use.

It is obvious that as the liquid is cured in, the pressure at the bottom will epcnd on, and increase in direct proportion to the height of the liquid in the mold. It is also obvious that as the ressure increases, the more the liquid will be forcedthrough the ioints, and the tighterthe joints must be to prevent it from escaping. I, therefore, provide that the limiting surface shall be composed of a number of relatively narrow horizontal members, to be erected in successive rows, so that the corresponding amount of 4 liquid may be poured back of each row as- Fig. IV, is a horizontal section of a.pre-

ferred form of a limiting piece to be used at the corners, showing the connection with the two sides.

Fig. V, is a vertical section of a preferred form of limiting surface showing how the adjacent strips are connected.

Fig. VI, is a horizontal section along the line VI, Vi, in Fig. 11.

Fig. VII, shows in perspective a block i used for holding in place the uppermost strip of the lining. I

Fig. VIII, is a detail illustrating the adjusting means for the uprights which form the backing for the ten iporary limiting surface. 1

The upright concrete Wall 1, has wire cleats 2, set in it at proper intervals. This preferably accomplished by' embedding the clcat l'a'ct'ore the concretehus set. To the free ends of these. wire cleats is attached a sheet oi expanded metal lathing 4-, or some similar supporting lathiug, properly SPlHl'll from the wall as by interposition of angle irons as bestsocn in Fig. III. The limitupper surface ii-L mg structure is then erected at the proper distance from the wall.

In order to support the limiting surface I employ upright supporting members, com prising ladders 10, erected in substantially vertical position and at right angles to the wall or surface to be lined. These ladders are supported by braces 11, arranged. so as to hold the ladders ri id and immovable. Planks 12, may then rungs 13 to form a working platform and be moved upward as the work progresses, see Fi II.-

Upright bars 16, are adjustably secured to the ladders, and find their attachment-by .means of a plurality of devices 17, illus'-- trated in detail in-Fig. VIII.

Each of these devices comprises a bolt 18, rigidly secured to the bar 16, and adapted to be slidably received within a bushing 19, in the side rail 20, of the ladder. The belt is of such length as to protrude a. considerable distance beyond the rail 20, and threaded to receive a wing nut 21. This wing nut is provided with an integral flange 22. which is held fromlateral movement by a plate 23, but is capable of rotary motion therein. By this construction the bars 16. may be moved laterally-with respect to the ladders 10, and the front edges of these bars may thereby be accurately adjusted in parallel relation to,

the wall to which the plastic is to be applied, regardless of any inaccuracies in any other-parts 01 the supporting structure. The bars 16. serve as a backing for the temporary lin'iit-ing surface forthe plastic lining, and the spacing distance from the wall is equal to the width of this limiting surface, plus the proposed thickness of the plastic. lining.

The trmporary limiting surface comprises limiting members prct'crably. in the form of horizontal plates lit), which are interchangeable and .iforincd with iutcrlitting edges. They may be of uuy suitable material, but preferably of sheet metal. llach plate (Fig. is made with a smooth limiting surface ill. and inwardly projcct lug uppcr and lower llaiigcs lrl. and 233. which form rcspcctircly the uppcr and lowcr cllg'cs oi the plutc. The ol' the uppcr' llauglo and the lowcr surlacc. 1? of the lowcr things, are complcnicntary and provided with a similar angular bend of V-shapcd cross-scetion, so that when one plalc is placcil on top o'l" another. 'the joint between the two will be tight and snug, and the two outer surl'accs 3L will lie in. the same plane and l'orm one 'continuous and smooth surface. The flanges Q 2. and iii, are of such l'orm and thickness as to admit of being clumped lo gct'hcr by the clamps CHL which may be tighl'cnotl by the thumb screw 3T.

At each (ind of those horizontal platcs are vertical flanges 38, 36, which cxtcml-lu'icke placed upon thecorner pieces. They are wardly from the smooth surface 31, and at right angles thereto. These flanges are so formed that abutting plates may be clamped. together end to end.

Corner pieces 50, (Figs. 1 and IV) are provided with similar flanges 51, so that they may be clamped directly to the hori' zontal plates 30. The outer surface 52, of the corner piece is made to conform to the shape desired for turning the corner. These corner pieces need not necessarily be made the same height as the side plates. It is referable that they should be of a greater ieight, since several side plates may then be secured to one end piece, resulting in greater stability for the whole.

I also provide retaining blocks 60, (Fig. VII) composed of a block 61, whose lower surface 62, is cut to engage the upper surface of the uppermost horizontal member. and arms 64, extending from either side of the block 61, which are arranged to fit on either side of the bar 16. enable the. block to he slid up and-down the bar 16, and a thumb screw 65, by means of which the block may be set in position upon the bar 16. See J? ig. VI.

In operation a single course of horizontal plates 30, is first placed in position between the wall and the bar 16, extending around the base line of the surface to be lined. The plates are clamped end to end, and to the down against the floor or bottom, adjacent the surface to be lined, and are held in their position by properly adjusted retaining blocks 60, which perform the double function of holding the plates tight against the bar 16, and also tight against the floor or bottom. This block must exert pressure sufficient to form a joint so tight that none of the liquid shall be able to leak out, and escape between the lower edge of the horizontal members and the bottom. The liquid is then poured in and allowed to'eool and set. When sufiieiently set, blocks v60, are removed and another course of horizontal plates 30, placed on top of the ones already in place and clamped thereto by the clamps 36. The retaining blocks 60,v are then put in place on top of the new plates and the operation repeated until \the entire wall is lined.

By applying the bituminous material in successive layers it will be seen that the pressure at any one point is at no time greater than that. cxcrted by a column of liquid of height equal to the depth of the plate 30. This depth is therefore made such that the pressure exerted by a column of liquid of that height will not be such as to penetrate between the upper and lower flanges when pressed togctl-icr by the clamps 36, and re-- taining blocks 60.

A lining thus constructed, provides a i other similar materials which r novel, useful and practical means for applying a 1i uid to a vertical or inclined wall. It also as the advantage of being easily put into place, and removed, and is capable of being used many times. It is also readil portable, and maybe used in applying suc gategial to structures of almostany size or e1g t. v i 11 have spoken of the material to be ap plied as bituminous, but it will be understood that my invention is applicable to uire to be poured ina state so liquid as to e diflicult of retention in position until they set.

Having thus described my invention, I claim 1. A temporary structure oft-he class described comprising a series of uprights,
